I installed a preinstalled ubuntu 12.04 desktop root fs archive on SD card and booting it on my new Chrome book. I was able to boot and see the Ubuntu Login screen and able to login as guest. But how can I login as a real user on that system? Or how do I create one if there isn't any user yet?
The ubuntu desktop root fs I used was ubuntu-12.04-preinstalled-desktop-armhf+ac100.tar.gz from this site: http://cdimage.ubuntu.com/releases/12.04/release/
